one thing is what you think is fair, and a whole 'nother thing is what the person with the item you want thinks he/she deserves.

economy is based in what people need. if in your server nobody wants a Warrior Set, and someone has a Killer Set for sale, he surely wont trade, because then he wont be able to get money out of the Warrior Set as he would with the Killer Set.

I'm telling you this, because in my server, there's like 3-4 people hanging around with Warrior Sets, me being one of them.

then again, if someone has a crapload of spare sets and he doesnt care about selling, that person would probably trade with no problems.

that being said, good luck. hope you find that person with spare sets.
